i'm looking at the motorola ones because i like the design. any recommendations?

Yup. Design and price should be lower down on your list. I'd place performance and fit at the top. Good headsets aren't always the most expensive. I've spent a lot on Motorola headsets (mostly the older ones like the HS810 and HS850) that performed worse than options that were far less expensive. Also keep in mind that phone conversations are bidirectional. Yes, you want to be able to hear your callers well but you also want them to be able to hear you well. The latter is often overlooked when people review or recommend headsets.

That is, unless you just want to wear it to be seen.

I've been very happy with the Plantronics Voyager 510. Great audio both ways and it fits me well but fit is very subjective. There are tons and tons of threads (try the Bluetooth forum) already on many headset options out there.

I use a Blue Eagle headset. I'm a truck driver and my wife can not hear any background noise while I'm driving. They can be purchased at TA truck stops and cost around $99.00. It comes with a home and car charger.

If you go looking, don't by the Blue Parroit. The Blue Eagle is heads above it.

I had an old Plantronics that worked really well - so well in fact, that my wife stole it. I never found a model # off of it, but I got it through a Cingular store around the corner. BAck then it was about $60 - so now it's probably less. I haven't come across the same one, so I finally broke down and ordered the BlueAnt Z9 from Buy.com. Free shipping & Google Checkout coupon = $60 roughly. I ordered last night regular ground delivery. Status says out for delivery here in Phoenix! Woo woo! Gotta love when you accidently live in the city they drop ship from!

I had the Plantronics 650 Voyager and it was awesome. I gave it to my dad and bought the Blue Ant Z9 with dual-mics, and it is by far my favorite headset. Decent battery life, very comfortable, small, stylish, and excellent call quality. It is $99 at Best Buy, and well worth the money. The only downfall between the Z9 and the Motorola's is the propriety dock connector, so you can't use the BlackBerry car charger to charge the headset. Other than that... wow.
